LEvnn VIAL HOLDER.

Application filed March 31, 192?. SeriaiNo. 179,774.

. cisely similar form at the opposite end of the sight opening and that will permit of providing a firm and reliable supporting connection with said stock or body. 7

In the accompanying draw1ng:-

Figure 1 is a side elevation of a carpentefls level embodying my invention.

Figure 2 is a similar view, on an enlarged scale and in part broken away, showing the middle sight opening and one of the end openings and the adjacent parts.

Figure 3 is a similar viewoi the same end with the front level vial holder removed from each of the sight openings. 7

Figure 1 is a vertical sectional view through the middle sight opening on the line es. oi Fi 2.

igure 5 is a horizontal sectional view on the line 5-5 of Fig. 2. V

Figure 6 is an end elevation of one of the holders. a

Figure .7 is a plan view of the same.

My improved level vial holder is particularly adapted for use with a stock or body 10 that is made of wood, said stock being provided with transverse sight openings for the display of the. level-vials, the openings, as shown, comprising the opening 11 at the middle and the two openings 11 located one on eachside thereof, adjacent the ends of the stock.

At each opening are displayed a pair of level vials, for alternative use, consisting of the vials 12 at the middle opening 11 and directed generally longitudinally for horizontal use, and the vials 12 in the end openings 11, directed generally cross-Wise and adapted for vertical use of the level.

The sight openings have their borders covered each by an apertured cover-plate 13 that is held in place by a pair of end screws 14 and that preferably is housed within a dere ssion 15 in the material of the stock, whereliy said plate lies substantially flush with the face of the stock. A cover-plate 13 is provided for each of the sight openings 11 and 11 and also for each side of said openings. and-the different plates are generally similar one to the other.

The bearing portion within the depression 15 for the cover-plate 13 is continuous and unbroken around the border edges of said plate 13 and comprises relatively wide portions 16 at the ends, which receive the end screws 14, and narrow connecting portions 17 at the top and bottom.

The material that is bordered by said hearing portion and intermediate the same and the border walls of the sightopening 11 or 11, as the case may be, is furthercut away or recessed so as to provide on each .SlClQ and T01 each openlng a second complete, continuons, and unbroken bearingrportiion, bearing face, or seat 18;

Said seat 18 comprises relatively wide por.

tions 19 at the ends and inter-connecting narrow portions 20 at the top and bottom.

' Between the seats 18 on the opposite sides for each ope ling thereremains'aweb-like structure 20 of the material of the stock 10 that is of appreciable thickness and that borders the sight opening 11 or 11', said web 20 being located symn'ietrically, relative to the middle longitudinal plane of the stock 10.

At each end seat portion 19 are provided a pair of holes 21 positioned one oneach side of the horizontal longitudinalplane, for the bolts 22 that hold the holders or 23 in place, there being two bolts for each holder and nuts 2% being provided for the bolts.

As will be noted, the bolts 22 for each individual holder 28 or 2 8 are located along a diagonal relatively to the sight opening 11 or 11*.

The holders 23 forthe vials 12 at themiddle opening 11 and the holders 23 for the vials 12 at the end openings 11 dilfer in details only to the extent needed to correspond to the differences in the positions of the vials. I V 7 Considering the details for the parts that are located at the middle'sight opening 11,. each of the two holders 23 comprises a supporting plate or web 25 that is opposedto the seat 18 and has at the ends the diagonally located openings 26 for the bolts 22. A central opening discloses the vials 12 and there may be provided as a finish or frame for said opening 27 an outwardly projecting border. rib or rim 28. The holes 21 are slightly large for the bolts 22 for purpose of adjustment as to accuracy of the vials.

As described, theportions 29 of the supporting plate or web 25 that cooperate with the holding bolts 22 are located alonga diagonal line or plane that extends across the horizontal longitudinal plane. The bolt holes 21 and bolts 22 tor the supporting plateor \vebq25 that mounted, on the opposite face of the stoclelO are also located along a diagonal. the two diagonals being symmetrically related to said horizontal plane.

The structure described permits ol making the opposed and mating holders :23 precisely-- alike.

Each holder 23 supports a single rial 12 so that the same is positioned syu'imetrically relative to the mating ,vial relative to both the horizontal longitudinal plane and the vertical axial plane. The actual support is provided by an inwardly directed structure in the form of an extension from the inner face of the supporting plate 25 so as to provide a pair of lugs 31 that have openings 32 for receiving and supporting the respectivcends of: the glass 12.

The vial suppt'irting' lugs 31 are entered into position within thetuiening 11 from 0pposite sides; the plates '25 engage withythe The holders. are preferably made of castaluminuin.

In the. structure shown and described two sight openings 11 are provided for vertical use. In longer'levels more of such openings, each having the proper vials, Ina Y be used.

As shown in Fig. I, the 'lll) or run 28 projects outwardly l'roin the face of tlu-welrflfi. The opening- 2? has as its burden wall tile/inaterial of said rib or riin 28 and the web 25. In some cases this llltltlil'lttlyllltly be recessed. suitably to receivea'window glassso as to serve as a closure for the opening 2?,the glass being held in place in any proper manner, as by the use or putty or the like, with a finish of tll'lHHlDt-Ut-t paint or the like.

Thus, with the two holders in use for a particular opening-the opening will he substautially closed.

I claim as: my invention 1. In a leveha stock of wood provided with' an elongated opening for lcVtllVlfllSHlltl haw ing at the inner peripheral surface of the ends at said opening a supporting web, said web having faces on the opposite sides that serve as seats, a pair of plates, each in the form of a border for said openingz; positioned one on each side of said stock, and having ex-t tensions at the ends that are opposed respec-i tivelv to said seats, bolts 'projected through said web and engaged With saidextensions: 'l'or holdin said plates said plates being pro-- vided with integral lu J for supporting, level rials. said extension in each case covering only a portion of the adjacent seat to which it. is opposed. the extension of th'eplate on oneside being generally on the opposite sidezol the longitudinal axial plane relatively to tho extension of the plate on the opposite side, i whereby unobstructed portions 01 said seats are available for use of tine-holdingbolts.

2. In a level-as described in claim l, the. extensions at the two ends of each of said plates being, located generally on the opp! site sides 01 said plane, whereby the holding. R0

bolts for each-individual plate can be locatedn alongtthe extension of a diameter of saidi openi n "a 1 PAUL H. IVTJGIEL.
